Safety

Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

7. Do not install near any heat sources such as radiators, heat registers, stoves, or other

apparatus (including amplifiers) that produce heat.

8. Only use attachments/accessories specified by the manufacturer.

9. Do not expose this apparatus to dripping or splashing and ensure that no objects filled

with liquids, such as vases, are placed on this apparatus.

Old electrical and electronic appliances

Electrical or electronic devices that are no longer serviceable must be collected separately and

sent for environmentally compatible recycling (in accordance with the European Waste

Electrical and Electronic Equipment Directive).

To dispose of old electrical or electronic devices, you should use the return and collection

systems put in place in the country concerned.

Precautions

Do not use Electro-Voice loudspeakers in an environment where temperatures

are below 0°C (32°F) or exceed +40°C (104°F).

Never expose an Electro-Voice loudspeaker to rain, water, or high moisture.

Electro-Voice loudspeakers are easily capable of generating sound pressure

levels sufficient to cause permanent hearing damage to anyone within normal

coverage distance. Caution should be taken to avoid prolonged exposure to

sound pressure levels exceeding 90 dB.

Suspension

Warning!

Suspending any object is potentially dangerous and should only be attempted by individuals

who have a thorough knowledge of the techniques and regulations of suspending objects

overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into

account all current national, federal, state, and local laws and regulations. It is the

responsibility of the installer to ensure all loudspeakers are safely installed in accordance

with all such requirements. When loudspeakers are suspended, Electro-Voice strongly

recommends the system be inspected at least once per year or as laws and regulations

require. If any sign of weakness or damage is detected, remedial action should be taken

immediately. The user is responsible for making sure the wall, ceiling, or structure is capable

of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker

not associated with Electro-Voice is the responsibility of others.

Description

Thank you for choosing an Electro-Voice passive loudspeaker system. Please take time to

consult the manual to understand all the features built into your EV system and fully utilize its

performance capabilities.

The EKX series is the newest member of the Electro-Voice portable loudspeaker family, and

combines legendary EV sound quality and reliability with the latest technology — all in a

compact package suitable for a wide range of sound reinforcement scenarios, including

musicians/DJs and live/club/installed sound applications. The EKX series features eight (8)

models (four (4) powered and four (4) passive), including 12-inch and 15-inch two-way

models and 15-inch and 18-inch subwoofers.

EV-engineered components, Signal Synchronized Transducers (SST) waveguide design

provides precise coverage and superior sound quality at high SPLs. EV’s award-winning

industrial design — with robust wood enclosures and durable EVCoat finish — ensures that EKX

speakers look as great as they sound.

Passive EKX models deliver up to 134 dB SPL utilizing high-sensitivity transducers designed

and engineered by EV (12-inch EVS-12M woofer / 15-inch EVS-15M woofer, each coupled with

a DH-1M 1-inch titanium compression driver; 15-inch EVS-15C subwoofer / 18-inch EVS-18C

subwoofer).

EKX passive models are ideal for portable and installed applications, with lightweight and

compact 15-mm wood enclosures with internal bracing, durable EVCoat finish, eight (8) M10

threaded mounting points (full-range only), aluminum pole-mounts, and all-metal handles.

1. Place the tripod stand on a level stable surface.

▪Fully extend the legs on the tripod stand.

▪Do not compromise the tripod stands structural integrity by trying to make the stand

taller.

▪Do not attempt to suspend more than one (1) loudspeaker on a stand designed for a

single loudspeaker.

2. Using two (2) hands lift the loudspeaker.

3. Set the pole cup located on the bottom of the loudspeaker onto the pole.
